2004 Audi A4 1.8L Petrol · N27 DAL

The most recent MOT, dated 18 November 2025, was recorded as a Pass, but it still listed a number of minor and advisory items – a non‑functional nearside rear registration‑plate lamp, slight condensation in both headlamp lenses and a minor exhaust leak. Looking back over the last three years the vehicle has alternated between Pass and Fail, with two outright failures in 2024 and 2025 that highlighted a severely worn off‑side front upper suspension arm ball joint, a deep cut on the nearside front tyre and recurring tyre‑wear advisories. The pattern shows that while the car can be made road‑worthy for the test, several core wear items have not been permanently rectified, indicating a maintenance record that is more reactive than proactive and a trend that is currently worsening rather than stabilising. At 133,116 miles the car averages roughly 6,000 miles per year, a figure that sits comfortably within the normal UK usage envelope for a 22‑year‑old saloon. The relatively modest annual mileage suggests periods of low utilisation or extended storage, which can be as detrimental as high mileage because rubber compounds, seals and battery plates deteriorate with age regardless of distance travelled. Nevertheless, the cumulative mileage is sufficient for wear on suspension bushings, brake discs, tyres and the timing belt to be approaching the end of their design life, and any components that have been subject to intermittent loading may be showing accelerated fatigue. A prospective buyer should give particular attention to the front suspension and steering assembly. The off‑side front upper ball joint was recorded as excessively worn in 2025; listen for clunking or a loose feel when the steering wheel is turned at low speed and check for uneven tyre wear that could indicate mis‑alignment. The nearside front tyre was flagged with a deep cut that reached the ply – this tyre must be replaced immediately and the wheel rim inspected for damage. The front brake disc was noted as pitted and the rear brake pads as thin, so a thorough inspection of disc surface for scoring and measurement of pad thickness is essential; any pulsation or shudder under braking would confirm the need for resurfacing or replacement. The oil‑leak advisory, present in both 2024 entries, should be traced to its source – common culprits on this model are the valve cover gasket or the oil filter housing – and the leak should be repaired before it becomes excessive. The minor exhaust leak should be examined for cracked manifolds or loose connections, as even a small leak can raise emissions and produce a noticeable rattle. Lighting faults (nearside rear plate lamp, front position lamp and headlamp lens condensation) are inexpensive to cure but must be rectified to avoid future failures. Given the car’s age, the buyer should also perform age‑related checks irrespective of mileage. Inspect all tyre sidewalls for cracking, dry rot or hardening, especially if the vehicle has spent long periods stationary. Examine the battery for sulphation and verify that it holds charge; a 12‑volt unit over 10 years old is likely to need replacement. Look for corrosion on the rear sub‑frame and any signs of rust on wheel arches, suspension mounts and under‑body panels, as the MOT noted sub‑frame corrosion that, while not yet critical, could progress. Verify that the timing belt (or timing chain on certain engines) has been replaced in accordance with the manufacturer’s interval – for a 2004 Audi A4 this is typically around 80‑100 000 miles – and inspect coolant hoses, brake fluid and power‑steering fluid for signs of ageing or contamination. A full service history, with stamps for oil changes, filter replacements and major component overhauls, will give confidence that the car has been maintained beyond the minimum legal standards and will help the buyer budget for the inevitable wear‑item replacements that accompany a vehicle of this vintage.
